19-year-old Soulja Boy shot to fame in 2007 with the huge popularity of his first single "Crank That" which sparked an accompanying dance craze and became a Hot 100 No. 1 and the top-selling digital track of the year thanks in large part to so many people first watching the clip on YouTube and checking out the music on MySpace. In the three years since, Soulja has notched three more Hot 100 top 20 singles, a pair of albums that hit No. 1 and 2 on the Rap Albums chart, and collaborations with Sean Kingston, T.I. and Gucci Mane. Recently, he's also worked with Kanye West, Snoop Dogg and 8Ball & MJG.

"I was one of the first artists to have a YouTube account, if not the first. I joined two months after the site launched," Soulja Boy told Billboard in 2008 about his hefty online presence, which initially helped him gain his large number of fans. Now, he's a fixture on Twitter as well (@souljaboytellem has over 2 million followers and he tweets every day), so he was ready for your tweeted questions about his hits and the new music he's getting ready for 2010.
